Jackson family roots

[raingirl]

It says there that both Joe and Katherine had Indian (Native American) in them. I thought it was only Joe who had NA in him.
Cool.
I was just wondering is this accurate?

Joseph Walter Jackson was born on July 26, 1929 in Fountain Hill, Arkansas. Joseph's family were descended of both African slaves and Choctaw Indians. When Joe was twelve, his parents split up and Joe and his father, Samuel Jackson, moved to Oakland. After graduating from high school, Joe left California, where he had a short career as a boxer, and moved to East Chicago, Indiana to take care of his mother. It was there that he met Katherine Scruse (born May 4, 1930), an Alabama native who was raised in East Chicago from age four. Katherine's family came from Alabama and are descended of African slaves of the Cherokee Indians.
